11 Claims.

part of the stove is practically indiscernible insofar as concerns the outward appearance of the stove, and at the sametime the range retains the characteristic lines and dimensions of modem stoves not equipped with such heaters.

Another object of the invention is to provide a stove havinga heater of the character described,

in which the arrangement for the introduction of air for heating and for burning and the outlet of the heated air and of the burned products, is

conducive to emciency oi operation of the heater .as well as aifording the desiredincorporation of the heater with the other elements of the stove.

A further obiect of the invention is to provide a means of affording delivery of cool air from the bottom of the stove to the gas control cocks and handles by way of the portion of the stove beneath the top gas burner chamber without sacrificing any of the space in said portion or in any way interfering with the full use of, such space for the purpose adapted.

The invention, possesses other objects and features of advantage, some of which, with the foregoing, will be set forth -in the following description of the preferred form of the invention which is, illustrated in the drawing\accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and description may be adopted within the scope of the invention as set forth in the claims.

- Referring to said drawing:

Figure 1 is a perspective view of a range constructed in accordance with my invention.

Figure 2 is a fragmen iy vertical sectional view taken of'the range, e plane of the section being indicated by the line 2-2 of Figure 1.

Figure 3 is a fragmentary vertical sectional view of the front portion of the stove taken at right angles in Figure 2; the plane of the section being indicated by the line 3-! of Figure 1.

Figure 4 is a horizontal sectional view of the range taken ongthe line 1-4 oi Figure 2.-

Figure 5 is a fragmentary vertical, section similar to Figure/3, but taken on the line 5-,! of

Figure 1.

In the embodiment of the invention illustrated,

the range, as aforesaid, is of the table top type, that iswith all of the stove elements including the oven 1 and broiler 4 arranged below the level of the cooking top 5 and de i8ned to be superimposed by a-cover-plate I made up desirably of a pair of sections I and 9, the latter of which is hinged or otherwise mountedto permit of its being readily raised from or lowered down over the cookingtop I. The oven and broiler compartments are located beneath the'section I and have provided at the front thereof doors I! and 1! respectively. 1 a

Covered bythe cooking plate I is a top gas burner chamber H in which is disposed burners it for heating the vessels on the plate. Beneath the chamber I4 and arranged in side by side relation is a warming compartment or closet l1 and a heater compartment ll, theformer being located betweenthe heater compartment and the oven and broiler while the latter is positioned to lie at the side of the range with the side wall i9 thereof preferably defining a' side end of the range. As here shown, the warming closet and heater compartment are coextensive in vertical length and are together coextensive in width and depth with the top gas burner chamber. A wall 20 separates the warming closet from the heater compartment and suitable'runners 2|, or the like are provided in the closet for-the support of a pair of horizontally slidable drawers 2! and 23 arranged one above the other and movable into and out of the closet through the front opening 24 thereof. The compartment I1 is heated by the heat in compartment II and to some extent by the oven and broiler, and serves both as a warming and a utility compartment. I

1 Within the compartment ll is a relatively narrow vertical shell or casing 26 which provides a combustion chamber and extends, as here shown, practically from the front of the compartment to the rear wall 21 thereof. The casing, as will be clear-from the drawing, is provided with a front wall 80 which is positioned inwardly of the forward edges of the walls I! and 20, and the casing 26 is spaced somewhat inwardlyfrom the I the bottom frame 20 of the range, to a point well up near the top of the compartment and is provided adiacentthe bottom of the front SI flue connection "attire rearof the range. An'

important feature is the location and arrangement of the outlet opening ll for the air heated and circulating through the heater compartment. Aswill be clear from Figures land Zsuch opening is located in the wall ilandtakes up practically the entire upper half ofthe wall so as to leavesubstantially exposed most of the upper half of the casing II, By reasonof the size and positioning of the not only is 7 there permitted a free discharge of-the air but a large area for the mom effective heating by direct radiation is afforded. Desirably the opening is engaged by a grill 8. ofornamental nature, and a rack I! for supporting dish towels, etc., for drying over the opening, is pivotally securedtotherearwallofthestoveandarranged for normal positi nin at the side of. the stove directly above the opening.

It is to be particularly notedthat since the heater unit or casing 28 la so relatively narrow,

the width ofthecompartment ll isrequired to be butasmallportionofthehoriaontalspacebeneaththetopgaslmrnerchamber. In'thismannerpracticailyallofthespacebeneaththetop gasburnerchamber remainsavailableforuseas awarmingclosetandnoincreaseinthewidthof the range is necessary for accommodating the heater. 7/

Inorderthattherangewillretaininappearaneetheeflectofcompactnesssuchasisso necessary, particularly in the table top type, of stove, I arrange for covering the closet and heater compartment area at the front of the stove withthesamemanhers. Aswillbeseenfrmn 'I'igure '1, the drawers 2! and It are provided with front panels II and SI respectively, which to gether provide a complete closure for the closet when the drawers are fully inserted therein. The panels however, are not only large enough to enclose the warming closet, but are made wide enough so as to completely cover the entire front of the heater compartment as well. In accordancewith the-foregoing each panel isextended at the end adjacent the heater compartment an amount equal to the width of the latter and thus both panels in horizontal dimension will be ccextensive and completely harmonise with the pandorcoveringll infrontofthe topgasburnerchamber. Itisimportanttonotethatwith thisarrangementthere needbebutasinglevertical division line across the entire'front of the stove, and since the panel I. andthe broiler door are co-terminous at the bottom and the meeting'adges of the oven and broiler doors are arrangedtnbeinhorinontalregistratiomconsiderable harmony in the horlaontal division lines is also maintained.

Aawillbeclearfrom m3 ands, the spice ll lemme 21,4ae I tioned off-at least in part-from the portion of thechamberinwhichtheburnersarelocated, andsuchspacellisopenatthe bottomsothat airmayentersameandpassoutthroughthewclosed position very little air,\particularly the relatively cool air from adjacent the bottom of thestovewillilndit'swaytcthespacefl. Here-' tofore, it has been sometimes attempted to provide for this desired delivery of cool air by perforatin'g the bottom member of the drawer, but quite frequently inethe use of the stove such perforations become inadvertently covered with articles placed in the drawer and as a result the flow of cool air to said space is seriously curtailed. In accordance with m invention, the panels'for' the drawers areformed hollow or otherwise constructed to provide avertical passage, and the bottom member ioins the panelat a point'intermediate rows of openings I. and respectively disposed near the top, andhottom of the inner wall of each 'panel. With this construction air may enter the open bottom of the closet and find its way through the panelsto the space I! notwithstanding the fact that the drawers may be fully closed and the bottom members thereof entirely covered. In a somewhat similar way the air from adjacent the bottom of the stove may reach the portion of the space 42 over the'heater compartment. In this connection, it is to be noted that by reason of the we and positioning of the front wall 2. not only will the heat from the compartment be effectively confined to the in erior of the compartment, but a direct cold air e will be aflorded between such wall and the adjacent portion of the drawer panels even when the drawers are in fully closed position,'cold air being admitted to the lower portion of such e through the narrow space left between the side wall of the lower drawer and the adjacent vertical edge of the wall 28.

i It is to be noted that by utilizing the drawer panels "and I! for closing the area in front of the heater compartment, not only is the requirement for a separate door eliminated, but the attendant diiilculty of-providing a door knob or handle which would be practical and of a design in keeping with the long horizontally extending handles II on the panels and on the oven and broiler doors, does not arise.
